Is CBS Planning a Charlie Sheen Intervention?

After a year of bad behavior and a weekend bender in Vegas with porn stars, the “Two and a Half Men” star may have pushed the network’s patience too far

After a weekend bender in Las Vegas with porn stars, Charlie Sheen walked onto the set of “Two and A Half Men” Tuesday — and will reportedly have to deal with a very concerned CBS.

According to TMZ, the network and producers of the hit sitcom will have “discussions" Tuesday with the highest-paid star in TV about his behavior and the effect it is having on his health and the show.

Those discussion could just be a friendly chat between Executive Producer Chuck Lorre, the network and their star (at right, late last year) or it could be the beginning of another stint in a treatment facility for Bad Boy Charlie that could see the show shut down mid-season.

CBS referred calls to Warner Brothers Studio, which produces the show. A studio rep did not immediately respond to a request for comment.

Sheen's rep, Stan Rosenfield, said he saw reports all Tuesday morning that his client wouldn't make it to set — right up until he arrived. He suggested the worries have been blown out of proportion.

"I keep reading that Charlie Sheen did not show up for work today. I read those remarks two hours before his scheduled time of arrival. Charlie Sheen arrived at work today and is there as I send this," Rosenfield said in an email to TheWrap. "Memo to Chicken Little: The sky remains in place."

Sheen has had several encounters with the law and rehab over the years.

On Feb. 23, the actor, while awaiting court proceedings on his Christmas Day 2009 domestic violence incident with now-estranged wife Brooke Mueller, put himself in rehab as a “preventive measure."

Later, as Sheen’s legal troubles seemed to clear up and the actor re-signed for another two seasons of “Men,” Lorre admitted at a CBS event that "I was in denial through the whole process." The executive producer said he looked forward to the show’s future seasons “because we have a lot more stories to tell."

Back in July, Lorre, or CBS, probably didn’t mean the stories of Sheen in a rage in a NYC hotel suite with a porn star huddled in the bathroom, as happened on Oct. 26, the divorce from Mueller and the extortion lawsuits that followed, or the reports of drinking and trysts with more porn stars that came out of Sin City this past weekend.
